THE POWER SYSTEM OF THE

FUTURE. AVAILABLE TODAY.Electricity consumption will continue to grow rapidlyduring the coming decades. At the same time, concernsrelated to global warming and declining fossil fuelresources have created a need, supported by politicalpressure, to reduce carbon emissions through renewablepower. At present, renewable sources, hydropowerexcluded, cover a good 3% of total production, but theirshare is rapidly growing.

Providing intermittency problems can be efficiently

resolved, wind or solar based electricity offers greatpotential. The variability of wind and solar power createsnew challenges to power systems which cannot be solvedby any grid solution. Even small variations in wind speed which can happen many times per day within time framesof less than 15 minutes have a dramatic impact on windpower output. In power systems with high shares ofinstalled wind power capacity, this is a challenge whichthe system is not designed to handle.The existing power systems need to be complemented bydispatchable, dynamic capacity with the capability of

ensure a sustainable, reliable and affordable powersystem a dynamic capacity which corresponds to roughlyhalf of the installed intermittent power capacity isrequired.The existing power systems need to be complemented bydispatchable, dynamic capacity with the capability ofhandling frequent fast starts, stops and load ramps. Toensure a sustainable, reliable and affordable powersystem an amount of dynamic capacity whichcorresponds to roughly half of the installed intermittentpower capacity is required.BALANCING THE POWER SYSTEMWrtsils power plants enable transition to a modern,sustainable power system. The main corner-stones arevery high energy efficiency, outstanding operationalflexibility, and multi-fuel operation. For todays emerging6

low-carbon power systems, they balance large input

fluctuations of wind and solar power. They also providehigh efficiency base load, peak load, and load-followingpower, as well as super-fast grid reserves on a nationalpower system level.Wrtsils technology and power plant solutions havebeen developed to provide a unique combination ofvaluable features that enable new horizons for futuresustainable, reliable and affordable national powersystems. The applications range from stationary andfloating baseload power plants to dynamic grid stabilityand peak load services, as well as a wide variety ofindustrial self-generation applications.Reservoir hydropower, where available, and smart gridswith demand response, assist in the balancing task. Whencomplementing the power system with Wrtsilssolutions, all system balancing challenges can be solved,even with the maximised use of intermittent renewables.7

OPERATIONAL FLEXIBILITYBeing able to operate in multiple modes, from efficientbaseload power production to dynamic system balancingin combination with, for example, wind or solar power,Wrtsil power plants become a key factor in optimisingpower systems.They offer ultra fast, zero-emissions, non-spinning gridreserve for any contingency situation or grid black start.They can generate megawatts to the grid in less than aminute from start-up and reach full load in less than fiveminutes. They are designed to start and stop at the pushof a button time after time without impact onmaintenance.The multi-unit configuration allows plant availability andreliability of close to 100% , as well as highest possiblefirm capacity. They also ensure rapid load following andpeak load capability with fast frequency regulation and anefficient spinning reserve.Wrtsils plants are also easy to locate next to criticalload pockets, i.e. in cities, thanks to plant size, and lowemission and noise levels, and thus reduce the gridinvestment cost notably. The infrastructural requirementsare modest, with little or no water consumption, and lowpipeline gas pressure needed.8

ENERGY EFFICIENCYPower plants based on multiple generating units are farmore reliable and fuel efficient than single or several large power stations. They also serve efficiently on partload and in demanding ambient conditions, enabling highdispatch even in hot climates and at high altitudes. Wealso offer the highest available simple cycle energyefficiency of current technologies, 50% or more. With theFlexicycle solution the advantages of a flexible simplecycle plant are combined with the superb efficiency of acombined cycle plant.FUEL FLEXIBILITYWrtsils multi-fuel plants enable the continuous choiceof the most feasible fuel, including solutions for liquid andgaseous fuels as well as renewables. The possibilitiesgained from multi-fuel plants and fuel conversion solutionsrepresent a hedge for the future. The role of natural gas inpower generation is expected to grow significantly overthe coming years. Recent technical breakthroughs and thecommercialisation of shale gas have resulted in asubstantial extension of the perceived depletion time ofgas reserves, and have lowered the price of natural gas.With power plants running on gas, the 27% renewableenergy share target set for 2030 by entities like the EU iswithin reach.(read more on pp. 84 - 87)

The focus ofmodularisation is around the engine and inside the powerhouse, even though modules are also used elsewhere,starting with the unloading of fuel, lubricating oil and otherprocess-related items. By using predefined modularsolutions, Wrtsil can ensure that set performancetargets are reached.

62

Rapid installation time is one of the main benefits.

Prefabrication also ensures consistent high quality. Otherbenefits include the compact and predefined design forcontainer transportation, and the use of well-provencomponents from well-known suppliers. The use ofportfolio modules leads to higher documentation qualityduring the tender phase. When compared to carrying outsuch work on site, the controlled manufacturing, cleaning,and painting processes associated with modularisation,have a positive environmental impact. For our customers,modularised design means higher return of their powerplant investment.Some of the benefits of modularisation are:

A pre-designed solution that can be customised

to suit specific needs

Fast and easy installation on site

Proven design

Reliable and thorough quality control

Optimised piping layout

Compact assembly

Standardised connection interfaces

Optimised transport dimensions

EMISSIONS REDUCTIONAND MONITORINGWrtsil Power Plants maintains a high level of expertisein emission cleaning methods for power plant effluentsand stack emissions, in order to offer a variety of provenreduction technologies for different market needs.

EMISSIONS REDUCTION FOR GAS POWER

PLANTSSulphur dioxide (SO2) and particulate matter (PM)emissions are insignificant for power plants running onnatural gas. Nitrogen oxide (NOX) emissions are also low.DRY METHODS (PRIMARY)Wrtsil gas engines use a lean-burn combustionprocess. In this process, natural gas and air are premixedin a low fuel/air ratio (lambda 2-2.5) before being fed intothe cylinders. The lean-burn process efficiently reducesNOX emissions due to a lower combustion temperature.Another advantage with the lean-burn process is theincreased output and efficiency of the engine. Wrtsilgas engines have sufficiently low NOX emissions tocomply with most national/local regulations using leanburn primary method only.SELECTIVE CATALYTIC REDUCTION (SCR)In areas with more stringent control of NOX emissions theengines can be equipped with SCR units. In the SCR,NOX is reduced by a catalyst, combined with a reagentthat is either an aqueous solution of urea or ammonia.OXIDATION CATALYSTSGas (SG) engines and multi-fuel (DF) engines can beequipped with oxidation catalysts for the abatement ofcarbon monoxide (CO) and/or hydrocarbon (HC)emissions, if required by national regulations.

Humboldt, Eureka, California (10 x Wrtsil 18V50DF, 162 MW)

The multi-fuel DF engines can operate on light fuel oil as backup. The plant is equipped with combined SCRs and oxidationcatalysts and meets the strict Californian emission requirementsboth in gas and liquid fuel mode.

67

EMISSIONS REDUCTION FOR LIQUID FUEL

POWER PLANTSNitrogen oxides (NOX), sulphur dioxide (SO2) andparticulate matter (PM) are the main emissions of interestregarding stationary liquid fuel engines. SO2 and PMemissions are mainly related to the quality of the liquidfuel. Wrtsil liquid fuel engines have low carbonmonoxide (CO) and hydrocarbon (HC) emissions thanks totheir high thermal efficiency.Wrtsils liquid fuel power plants are designed to meetthe stack emission limits set by the World Bank/IFCGuidelines for liquid fuel power plants up to 300 MWth(~140MWe) in non-degraded airsheds by using dryprimary methods. Secondary flue gas treatment methodsare available for more strict regulations, or when only lowgrade liquid fuels are commercially available.DRY METHODS (PRIMARY)The primary method (Low NOx combustion process) usedin Wrtsil liquid fuel engines is designed for the bestoverall emissions performance, while maintaining thegood thermal efficiency of the engine. The main elementsof the Low NOx combustion process are:

Late fuel injection start

High compression ratio

Optimised combustion chamber

Optimised fuel injection rate profile

Early inlet valve closing (Miller concept) together

with high boost pressure.These are the key elements for suppressing thecombustion peak temperatures, resulting in reduced NOXformation.SELECTIVE CATALYTIC REDUCTION (SCR)Wrtsils liquid fuel power plants can be equipped withSCR units to reduce NOx emissions if required.

68

NOx emissions are typically reduced by up to 8090% by

using a reagent that is either an aqueous solution of ureaor ammonia. The composition and structure of thecatalyst element are selected based on fuel properties. Athigh reduction rates, the size of the SCR reactor increasesand more complicated premixing and reagent injectionsystems are needed. In addition the control systembecomes very critical due to operation within a narrowwindow.FLUE GAS DE-SULPHURISATION (FGD)Several FGD types are available for the power plantmarket. The most feasible methods in stationary engineplants have generally been proven to be wet sodiumhydroxide (NaOH) FGD in smaller plants, and wet calciumcarbonate (CaCO3) FGD in larger plants. Wet FGDsystems are typically capable of removing up to 90% ofthe SO2 emissions. All wet FGD solutions require largequantities of water and reagents.The FGD end products, either liquid or solid depending onthe chosen FGD technique, need to be disposed of in anenvironmentally acceptable way. The composition of theend product depends on the fuel oil used, lubrication oil,process water and reagents. The disposal and utilisationoptions available for the end product should be examinedin the environmental assessment of the project.ELECTROSTATIC PRECIPITATOR (ESP)A dry ESP unit can be used to reduce PM emissions. TheESP technique provides a stable, low pressure-loss optionto reduce PM emissions. ESPs dry end product, fly ash,needs to be disposed of in an environmentally acceptableway. The composition of the end product depends on thefuel and lubrication oil used. The disposal and utilisationoptions available for the end product should be examinedin the environmental assessment of the project.

69

CONTINUOUS EMISSIONS MONITORING (CEMS)

In cases where continuous data on emission levels isrequired, indicative or parametric emissions monitoringsystems will provide robust, good quality and costefficient emissions monitoring. In these systems,emissions are calculated based on process data, such asengine parameters, fuel composition and ambient data. Insome installations, continuous emissions monitoringsystems (CEMS) based on analysers are required.There are many different CEMS on the market and thechoice of system needs to take into careful considerationthe installations specific features, such as measuredcomponents, fuel and stack configuration. The integrationof emissions data handling and reporting into the plantsystem is a crucial part of a successful emissionsmonitoring system.

REDUCING CONTAMINATED WATER

The oily water collection and treatment system is anessential part of the engine power plant. The system isdesigned to collect water from areas that are potentiallycontaminated with oil and other impurities for treatment.Before discharge from the plant, contaminated water canbe either treated on-site by the Wrtsil oily watertreatment (OWT) unit or transported for proper treatment.In areas that are subject to stringent effluent limits,biological treatment might also be required. WrtsilSenitec Biosys is a biological treatment system for greywater, treated oily water and/or similar effluents frompower plants.

OPERATION OF A MULTIUNIT POWER PLANT

There are often significant seasonal, weekly and dailyvariations in power demand. In a multi-unit power plantthe units can be started and stopped as per demand. It ispossible to optimise the usage of each single unit bychoosing to either provide spinning reserve or to run it flat-out to obtain maximum efficiency.A multi-unit power plant can be run in various waysdependent on the situation at hand. Basically, there aretwo main operating principles:In spinning mode, the gensets are synchronized andrunning, but at a reduced load. This way the plant is fullyready to take large, immediate load increases just inseconds.In efficiency mode, the minimum amount of gensets arerunning at full load to meet the current load demand,thereby allowing them to operate at their best thermalefficiency. Still, the remaining gensets, which are in standby mode, can come online and reach full load in a matterof a few minutes to meet any unforeseen load increases.Plant features in the two different operation modes

COMBUSTION ENGINEMAINTENANCEMaintenance of gas, dual fuel and liquid fuel engines iseasy. Keeping strategic spare parts for exchangepurposes on site considerably reduces the downtimerequired for maintenance. All maintenance can beeffectively performed on site. One engine at a time can bemaintained, without affecting the operation of the otherunits of the plant.The multi-unit setup means that the annual average unitrunning hours, depending on the actual load profile, canbe considerably lower than the annual plant runninghours. In a multi-unit plant the units can be dispatched, sothat the running hours are unequally spread on each unit.This allows for scheduling the maintenance one unit at atime, thereby maximising the available power generationcapacity at any given time. Ideally, the maintenance isscheduled at periods of lower power demand.For Wrtsils combustion engines there is no equivalentoperating hours (EOH) calculation. This means that themaintenance schedule is not affected by the number ofstarts and stops.

79

MAINTENANCE SCHEDULINGThanks to condition-based, flexible maintenance, engineservicing can be performed when it best suits thecustomers operations. The following figures illustratethree different scheduling principles for the maintenanceof a Wrtsil power plant.Principle 1: One at a time Maximum firm capacity due to sequential maintenance

of one unit at a time

reliability and unsensitiveness to unschedulemaintenance outages thanks to multiple units

needed, by concentrating all maintenance in the offseason

Combining Principles 1 and 2:

Adjustable maintenance schedule suitable for seasonal

operating variations Allows fluctuating business to switch between the

maintenance profiles as needed

82

RELIABILITY & AVAILABILITY

Thanks to the multi-unit configuration, the highestavailability and reliability targets can be achieved.The below figure illustrates the typical operationalavailability of a Wrtsil power plant. If the plant capacitymatches the actual maximum load (corresponding to thepower generated by n units), the availability of the plantcapacity is above 96.5% . By adding a stand-by unit, theavailability can be increased to >99% , and a secondstand-by unit further raises the availability to >99.9%.

83

APPROVED FUELSWrtsil power plants are able to run on a wide selectionof fuels, ranging from natural gas to fuel-water emulsions.Detailed specifications for the approved fuels are availableupon request.

84

GASEOUS FUELS & LNG

NATURAL GASNatural gas consists mainly of methane plus smallquantities of heavier hydrocarbons, carbon dioxide andnitrogen. Commercial gasis processed to meetspecifications for heating value, Wobbe index andcleanliness.LIQUEFIED NATURAL GAS (LNG)LNG is natural gas that has been converted to liquid formfor easier transport and storage. LNG takes up about1/600th of the volume of natural gas in gaseous state.COAL BED NATURAL GASCoal bed natural gas is found in underground coal layers.It contains methane, water and carbon dioxide in varyingpropostions. Coal bed gas contains more heavierhydrocarbons than conventional natural gas, but nonatural gas condensate.SHALE GASShale gas is natural gas trapped in fine-grainedsedimentary rock, particularly quartz and calcite. Togetherwith coal bed gas and methane hydrates, shale gas is anunconventional source of natural gas.BIOGASBiogas is the result of treating organic matter in digestersor through other decomposing processes. The resultinggas consists mainly of methane and carbon dioxide.ASSOCIATED GASAssociated gas is separated from crude oil in fielddegassing equipment. The methane content is lower thanin natural gas, but the concentration of heavierhydrocarbons is higher, normally yielding a higher energydensity. GD engines are very suitable for burningassociated gas, also when operating in fuel sharing mode.85

LIQUID FUELSLIGHT FUEL OILLight fuel oils or diesel oils are high value distillates thathave traditionally been used to fuel diesel engine powerplants, both for stand-by operation and baseloadapplications. The use of light fuel oils in baseloadapplications has decreased since it has become possibleto use cheaper lower grade fuels. There are, however,certain applications, such as backup power plants, andinstallations on islands and in arctic conditions, wherelight fuel oil is still the preferred alternative.HEAVY FUEL OILHeavy fuel oils are blended products based on theresidues from refinery distillation and cracking processes.They are black viscous liquids which require heating forstorage and combustion. Heavy fuel oils are used fordiesel engines in power plant and marine applications.CRUDE OILCrude oil is a highly complex mixture of hydrocarbons andother components. The flash point of crude oil is low,typically below the ambient temperature. Crude oil can

86

also be used as fuel in power plants with diesel engines,

for example in oilfield power production. Anotherapplication is for pumping stations located along a crudeoil pipeline, where fuel from the pipeline can be used forthe prime movers.LIQUID BIOFUELSLiquid biofuels are derived from biological material andcan be produced from a variety of carbon sources.Common liquid biofuels approved for us e in Wrts ilengines include oils from various oilseeds, such as palmoil, palm stearin, rape seed oil, sunflower oil and jatrophaoil. Liquid biofuels can also be of non vegetable origin, i.e.oils or fats from fish, poultry and animals. Refined biofuelqualities, such as transesterified biodiesel orhydrogenated renewable diesel, can also be used.FUEL-WATER EMULSIONSAn oil-in-water type emulsion is one way of utilising theresidue coming from a refinery as fuel in a diesel powerplant. By making an emulsion with water the viscosity isdramatically reduced, enabling it to be pumped at ambienttemperature in warm countries. Using it in the dieselengine requires only a fraction of the heating needed forheavy fuel oil.

87

POWER PLANT GENSETS

The core of a power plant solution is the genset. Wrtsilgensets consist of a four-stroke medium-speed engine,connected to a generator via a flywheel and coupling,mounted on a common baseframe. The genset is aligned,fine-tuned and pre-tested in the factory, fully ready forinstallation with minimal work at site.

Small and medium sized gensets (based on

32/32TS/32GD/34DF/34SG) are normally transported ascomplete gensets. If required by the logistics of theproject, the gensets can also be delivered split into twoblocks: engines mounted on the baseframe andgenerators shipped separately.Larger gensets (based on 46/50/46GD/50DF/50SGengines) are normally delivered in two blocks: engine andgenerator mounted on its own base frames, ready to bebolted together at site. This allows a considerably reducedtransportation weight.88
